AUTOMATIC COMBINED ALARM AND STOP MECHANISM FOR CARDING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 581,548, dated April27, 1897.

Application filed May 9,1896. Serial No. 590,824. (No model.)

To all whom it may concern.-

Be it known that I, JACOB F. GEB,of Franklin, in the county of Norfolkand State of Massachusetts, have invented certain new and usefulImprovements in an Automatic Combined Alarm and Stop Mechanism forCarding-Machines,of which the following is a specification.

This invention relates to card-feedin g mechanism of the type known asthe Apperly feeder for carding-machines, and has for its object toprovide means whereby,in case of the breakage of the sliver, thecarding-machine will be automatically stopped when the reciprocatingtraveler of the said feeder reaches the end of its guideways; and afurther object of the invention is to combine with the stop mechanism analarm that will give notice at once of the breakage of the sliver. Theconstruction of an alarm or stop mechanism so as to act at the moment ofthe breakage of the sliver, whatever may be the position of thetraveler, involves the employment of some device or element extendingthe full length of the path of the traveler, and this tends tocomplicate the parts toa degree that is avoided by my present invention.Since the feeder supplies several lengths of sliver in advance of itsbeing taken up by the carding-machine, it is sufficient that the.

alarm operates at the end of the movement of the traveler, provided thecarding-machine is automatically stopped at the same time and does notdepend upon the attention of the operative being called to it by thealarm.

My present invention consists in the construction and combination ofparts, substantially as hereinafter described and claimed.

In the accompanying drawings, Figure 1 represents a side elevation of acarding-machine and a portion of an Apperly feeder, the same having myimprovements attached. Fig. 2 represents an enlarged detail sideelevation of the belt-shipper mechanism. Fig. 3 represents an elevationfrom the right of Fig. 2, the tubular guide and hand-lever being insection. Fig. 4 represents a plan view of the parts shown in Fig. 3.sents a detail front elevation of a portion of the feederhaving myimprovements, the trav- Fig. 5 repre- I eler being at the end of itsreciprocation and the sliver unbroken. Fig. 6 represents a sideelevation from the right of Fig. 5, the bracket forsupportin g thetripper device being shown in section to illustrate the insulation ofthe stud. Fig. 7 represents a view similar to Fig. 5, but with the partsin the position they occupy when the sliver is broken. Fig. 8 is adetail view illustrating a modification hereinafter described.

Similar reference-characters indicate the same parts throughout theseveral views.

The carding-machine (indicated at A in Fig. 1) requires no specificdescription in de tail, and the. same is true of the Apperly feeder,(indicated at B.) It is sufficient to state that the main shaft of thecarding-machine is provided with fast and loose pulleys a a, (indicatedin Figs. 2,3, and 4,) and that in the feeder there is the usual travelerI), provided with sockets b b, movable upon a fixed guide-rod b asliver-guide b and rolls 19 5 arranged to move along another guiderod.(Not shown.)

Pivoted to the traveler is a forked lever, one of the arms 0 of which ishook-shaped and engages the side of the sliver, passing through theguide 19 the other arm 0' extending in a substantially horizontaldirection. (See Fig. 5.) The forked lever is pivoted to swing laterallyor in a plane parallel with the path of movement of the traveler,whereby the arm 0 is adapted to impart a strong endwise thrust againstthe arm 9 of the lever e, presently described. A weight 0 servesto holdthe lever normally in the position shown in Fig. 5 and to turn theleverto the position indicated in Fig. 7 if the sliver breaks. The limits ofmovement of the lever are determined by one or more stop-pins oprojecting from the traveler.

A bracket d is secured to the frame of the feeder at one end and isprovided with a vertical slot d, in which is secured the stem of a studd insulating-blocks d being interposed between the bracket and a collarof said stem on one side and a nut on the other side. On the outer endof the stud is pivoted a bell-crank lever e, the lower arm beingwidened, as at e, and the horizontal arm 6 having a hook c adjustablysecured therein, as by means of the nut 6 To the said hook is securedone end of a wire f, by means of which a belt-shipper is' operated, aswill be presently described. In order that this wire may take a coursewhere it will be out of the way, it is indicated as in three sectionsconnected to opposite ends of two bell'crank levers f in a well-knownmanner and as shown in Fig. 1.

An electric alarm-bell is indicated at g, said alarm being included inthe circuit of a battery or other source of electrical energy,(indicated at g.) One of the wires of the circuit leads to the stud dwhich is entirely insulated from the rest of the mechanism when themachine is working normally, and the other wire leads to some part ofthe frame of the machine. To complete the circuit, it is only necessarythat some part of the machine shall make contact with the stud (Z orsome part connected therewith. This takes place when the sliver breaks,and the weight 0 causes the arm 0 to swing from the position shown inFig. 5 to the position shown in Fig. 7 and come in contact with the arm6, pivoted to said stud. As above stated, this will occur at the end ofthe reciprocation of the traveler, and it will thus ring the alarm,owing to the connections above described. At the same time the movementof the lever 6, caused by the positive thrust imparted by the arm 0,carried by the traveler, exerts a strong pull 011 the wire, the extremeend of which is connected to a latch adapted to control the position ofthe belt-shipper, which will now be described.

A bracket h (see Figs. 1 to 4) is secured to the frame of the machine,as by bolts h, and supports a tubular guide 1', slotted at t" andcontaining a slide 1", having arms 2' projecting out through the slotand engaging the edges of the belt a To one end of the slide is secureda rod or stem '5", which extends out through the end of the guide, aspring be ing compressed between the end of the guide and a collar 2'and said spring being capable of moving the slide to shift the belt fromthe fast pulley Ct to the loose pulley a when permitted to do so. Theslide 2' is provided with a shoulder or notch which receives the end ofa spring bolt or latch L, the said latch bein g supported by a suitablebracket or frame attached to the guide t' and operating through asuitable opening in the latter. A lever k fulcrumed at if, is connectedto the outer end of the spring-latch at 71: and to the outer end of thislever 70 is secured the extreme end of the Wire f.

\Vhen the arm 0 engages the arm 6, as above described, due to thebreakage of the sliver, the positive pull on the wire f causes the latch71; to be withdrawn from engagement with the slide 2' and the latter isimmediately forced by the spring 11 to cause the arms to shift the beltonto the loose pulley, and thus stop the carding-machine.

The belt-shipper may be applied to any desired portion of the frame ofthe machine, or elsewhere, to accommodate a belt running from anoverhead shaft or pulley or one which runs from a shaft or pulley below,and the wire connections f may be readily altered to suit the change inlocation of the belt-shipper.

It is to be understood that the length of the arm 0 is such that itmakes its first contact with the arm e shortly before the travelerreaches the extreme limit of its movement in that direction and operatesthe alarm at the first contact. During the short remaining distance ofmovement of the traveler the power of the mechanism which moves thetraveler acts, through the connections described,to withdraw the latchfrom the springoperated belt-shipper. The certainty of action of thisconstruction renders it a preferable one, but it is to be understoodthat I am not restricted to the mechanical connection between the arm 6and the spring-latch 76. For instance, in Fig. 8 I show the latch asprovided with a plate Z, forming the armature for an electromagnet Z.WVith this construction the wire f becomes simply part of an electricalcircuit, including said electromagnet and any suitable source ofelectrical energy. iVith this construction when the arm 0 makes contactwith the arm 6 it will instantly and simultaneously operate both theelectric alarm and the releasing-latch of the belt-shipper.

In order to operate the belt-shipper by hand, a lever m is pivoted to anarm projecting from the tubular guide and connected by means of a link mwith one of the arms i of the belt-shipper. This lever is employed tomove the slide in opposition to the spring when it is desired to startthe carding-machine.

I claim- 1. The combination with a cz'irding-machine and a feedmechanism therefor,which includes a reciprocating traveler, a weightedarm pivotally connected with the traveler, and arranged to be held inone position by a sliver passing through the traveler, a movable armlocated at the end of the frame of the feeding mechanism and insulatedtherefrom, and adapted to be operated by the said weighted arm when abreakage in the sliver occurs, an electrical alarm, the circuit of whichis adapted to be closed by the contact of the said movable arm andweighted arm, a belt-shipper for the cardinganachine, and connections between the said movable arm and belt-shipper whereby the latter isoperated by the former after the alarm is sounded.

2. The combination with a carding-machine having a belt-shipper, of thefeeder provided with a traveler, the forked lever pivoted to thetraveler so as to oscillate in a plane parallel with the path ofmovement of said traveler and having the arm 0 extending in thedirection of said path of movement, the bell-crank lever e pivoted tothe frame of the feeder, and

the wire f connecting said bell-crank lever with the belt-shipper,substantially as described.

3. The combination with a carding-machine having a spring-actuatedbelt-shipper, of the feeder provided with a traveler, the forked of thefeeder, the spring-latch k for normally holding the belt-shipper inposition for the operation of the carding-machine, and the wire fconnecting said bell-crank lever 6 with I 5 the spring-latch 70,substantially as described.

In testimony whereof I have signed my name to this specification, in thepresence of two subscribing witnesses, this 6th day of May, A. D. 1896.
